Abstract
The utility model discloses a waterproof valve actuator, which comprises an actuator shell, a motor and a circuit board, wherein a baffle is arranged in the actuator shell, the baffle divides an inner cavity of the actuator shell into two parts and correspondingly forms two small cavities, the motor and the circuit board are respectively arranged in the two small cavities, waterproof glue is injected into the small cavity where the circuit board is positioned, and a sealing body which fills the small cavity space is formed after the waterproof glue is solidified and formed in the corresponding small cavity; the motor is fixed in a motor sealing shell, and the motor sealing shell is internally arranged in a corresponding small cavity. The waterproof sealing device has good sealing effect, the circuit board is directly sealed by waterproof glue to realize sealing, and the phenomenon that the circuit board burns out due to water leakage does not occur in the water draining operation after the production of the waterproof sealing device.
Description
Technical Field
The utility model relates to a waterproof valve actuator.
Background
Waterproof of valve actuator on the market at present generally sets up the seal groove on the actuator casing, then sets up O type circle sealing gasket in the seal groove, and the actuator cap passes through the screw and is fixed with the actuator casing after, realizes the sealed of motor and circuit board in the actuator casing. When the valve actuator is assembled, if the O-shaped ring is placed unevenly, the sealing is not tight, so that when the valve actuator is used for diving, a water leakage phenomenon exists between the actuator shell and the actuator shell cover, and once water enters the valve actuator, the circuit board can be burnt out.
Disclosure of Invention
The present utility model is directed to a waterproof valve actuator that solves the above-mentioned problems with the prior art.
The utility model adopts the technical scheme that:
the waterproof valve actuator comprises an actuator shell, a motor and a circuit board, wherein a partition plate is arranged in the actuator shell, the partition plate divides an inner cavity of the actuator shell into two parts and correspondingly forms two small cavities, the motor and the circuit board are respectively arranged in the two small cavities, waterproof glue is injected into the small cavity where the circuit board is located, and a sealing body which fills the small cavity space is formed after the waterproof glue is solidified and formed in the corresponding small cavity; the motor is fixed in a motor sealing shell, and the motor sealing shell is internally arranged in a corresponding small cavity.
Further, the motor sealing shell comprises a shell body and a cover plate, wherein a through hole is formed in the shell body, the through hole in the shell body is communicated with a through hole in the actuator shell body and is used for penetrating out a motor rotating shaft, the cover plate is fixedly connected with the shell body, and a sealing ring is arranged between the cover plate and the shell body.
The utility model has the following beneficial effects:
the waterproof sealing device has good sealing effect, the circuit board is directly sealed by waterproof glue to realize sealing, and the phenomenon that the circuit board burns out due to water leakage does not occur in the water draining operation after the production of the waterproof sealing device.
Drawings
Fig. 1 is a structural diagram of the present utility model.
Fig. 2 is a structural view of the actuator housing.
Description of the embodiments
The utility model is further described below with reference to the accompanying drawings.
Referring to fig. 1 and 2, the waterproof valve actuator of the present utility model comprises an actuator housing 1, a motor and a circuit board, wherein a partition 11 is disposed in the actuator housing 1, the partition 11 divides an inner cavity of the actuator housing 1 into two parts, and two small cavities 12 are correspondingly formed.
The motor and the circuit board are respectively arranged in the two small cavities 12, waterproof glue (sealing resin can be injected) is injected into the small cavity 12 where the circuit board is positioned, and the waterproof glue is solidified and molded in the corresponding small cavity 12 to form the sealing body 3 which fills the small cavity space.
The motor is fixed in a motor sealing shell 2, and the motor sealing shell 2 is arranged in a corresponding small cavity 12. The motor sealing shell 2 is consistent with the motor sealing shell structure adopted in the existing valve actuator, and comprises a shell 21 and a cover plate 22, wherein a through hole is formed in the shell 21, the through hole in the shell 21 is communicated with the through hole in the actuator shell 1 and is used for penetrating out a motor rotating shaft, the cover plate 22 is fixedly connected with the shell 21, and a sealing ring is arranged between the cover plate 22 and the shell 21.
The utility model seals the circuit board by adopting the waterproof glue, and when in use, the sealing ring between the actuator shell 1 and the actuator shell cover can be directly omitted, so that water leakage caused by poor assembly of the O-shaped ring in the existing structure is avoided. After the product is produced, the phenomenon that the circuit board is burnt out due to water leakage does not occur in the water discharging operation.
The foregoing is merely a preferred embodiment of the utility model, and it should be noted that modifications could be made by those skilled in the art without departing from the principles of the utility model, which modifications would also be considered to be within the scope of the utility model.
